this little thing showed up and doesn't want to go i tried everything i cant find any configure file i configure my hud via mod menu

It seems to happen when you join a world around the same time as a chat message is sent with Hide chat enabled and Show chat message indicator disabled. Enabling Show chat message indicator, waiting a few seconds for chat to clear, then disabling it again fixes the issue.
I can replicate it on singleplayer by setting up a repeating command block running say <message> then exiting and rejoining the world.

Interesting, thank you for the investigation! I will have a look.

tysm for the fix and amazing mod!

can confirm i have this issue aswell

Oh, I misunderstood. It gets stuck when it should never be rendered in the first place. I see, that makes some sense. I published a fix.

i solved the problem but god knows how.

If you can replicate this issue, please do let me know!
